Personally, I think this whole thing is silly. I don't think there should be a Wikipedia in Klingon, or Ferengi, or Pig-Latin, or any other pseudo-language. (In the immortal words of William Shatner, "Get a life!") If a few Trekkies want to start up a Klingon wiki, they can download the MediaWiki software themselves and install it on their own server. That's how I started the Disinfopedia. I didn't need to ask anyone else for permission, because I didn't use anyone else's resources (other than the software, which I thank the Wikipedia community for giving away free).
Having said this, though, perhaps a few folks here will enjoy taking a look at Google's language tools, which enable users to "Use the Google Interface in Your Language," with choices including "Elmer Fudd," "Pig Latin," "Esperanto," "Hacker," "Klingon" (of course), and something called "Bork, bork, bork!" The URL is:

Can we have a Wikipedia in Bork, bork, bork!, please? :-)
